Filter by:This study will evaluate the efficacy and safety of atezolizumab plus tiragolumab or atezolizumab alone following neoadjuvant chemoradiotherapy (nCRT) in participants with locally advanced rectal cancer (LARC). The study consists of a safety run-in phase and a randomization phase. Participants enrolled in the safety run-in phase will receive atezolizumab + tiragolumab following nCRT. Upon determination of the safety of the treatment regimen, the study will be proceed to the randomization phase. Participants will be randomized in a 1:1 ratio to the atezolizumab + tiragolumab arm or atezolizumab arm.
Data from a prior phase II study of single agent cabozantinib in metastatic, refractory colorectal cancer (NCT03542877) combined with the compelling preclinical data in colorectal mouse models utilizing cabozantinib combined with nivolumab have led to this concept for a clinical trial to combine cabozantinib and nivolumab in patients with metastatic MSS CRC in the third line setting and beyond.
The data will be obtained from 10 tertiary centers located in Poland (Cracow - coordinating center, Warsaw - 3 centers, Sosnowiec, Szczecin, Bydgoszcz, Lublin, Gdansk, Poznan) and 5 foreign centers. The analyses will include patients with rectal cancer operated on between 2013-2019. A database in MS Excel is prepared that consists of following data: - Type of neoadjuvant treatment (if any) - Time-interval between the end of neoadjuvant treatment and surgery - Type of surgery - Staging of rectal cancer i.e. (y)pTNM - Number of retrieved lymph nodes - Number of lymph nodes with metastases - R classification (R0, R1, R2) - Preoperative medications (metformin, statins, NSAIDs, anticoagulants) - Recurrence date and type (local, systemic, both diagnosed at the same time) - Date of death or date of last follow-up visit The aims of the study are following: 1. Establishing whether neoadjuvant treatment (PSCR or chemoradiotherapy) influences number of retrieved lymph nodes in rectal cancer 2. Establishing whether time-interval between the end of PSCR and surgery influences lymph node yield 3. Establishing the prognostic value of lymph node ratio - validation of the previously calculated cutoff point at the level of 0.41 4. Determining independent prognostic factors in rectal cancer - in particular related to medications taken before the operation, metformin and anti diabetic drugs in the first place
The ACO/ARO/AIO-21 investigator-driven, open-labeled, phase I drug re-purposing trial will assess whether the IL-1 receptor antagonist Anakinra can be safely combined with fluoropyrimidine-based chemoradiotherapy (CRT) in patients with rectal cancer.
The study is a multicenter, open-label, randomized controlled clinical study, and the purpose of the study is to compare the pathological complete response rate (PCR) of patients with locally advanced rectal cancer treated with short-term radiotherapy, sequential Camrelizumab and CAPOX (group A) to long-term concurrent chemoradiotherapy, sequential CAPOX (group B) in patients with LARC. A total of 230 patients were included in this study.
Background: Dehiscence of colorectal anastomosis is a serious complication associated with increased mortality and impaired functional and oncological outcomes. We hypothesised that anastomosis reinforcement and vacuum trans-anal drainage could eliminate some risk factors of colorectal anastomotic dehiscence,including mechanically stapled anastomosis instability and local infection.
The investigators evaluate the response of rectal cancer to neoadjuvant therapy and classify the response according to specific periods of time after the end of neoadjuvant treatment.
This research study is evaluating a program that entails remote monitoring and home-based care for people with cancer who are receiving chemotherapy, radiotherapy, or chemoradiotherapy.
A Phase II Study of Total Neoadjuvant Therapy for High-risk Locally Advanced Rectal Cancer
ERUS-3D and CMI demonstrated good diagnostic accuracy in parietal staging of rectal extraperitoneal neoplasms, however with greater efficiency of the endoscopic method. The association of studies can improve diagnostic efficacy and influence the most appropriate approach.
